Why Security Matters

A single security breach can destroy years of trust. In 2025, the average cost of a data breach reached $4.88 million. Prevention is far cheaper than remediation.

The OWASP Top 10

The Open Web Application Security Project maintains a list of the most critical security risks. Here's how we protect against each:

1. Broken Access Control

Risk: Users accessing data or functions they shouldn't.

Our Protection:

  • Role-based access control (RBAC)
  • Server-side authorization checks
  • Deny by default policies
  • Comprehensive audit logging

2. Cryptographic Failures

Risk: Sensitive data exposed due to weak encryption.

Our Protection:

  • TLS 1.3 for all data in transit
  • AES-256 for data at rest
  • Secure key management
  • No sensitive data in URLs or logs

3. Injection

Risk: Malicious code executed through user input.

Our Protection:

  • Parameterized queries (never string concatenation)
  • Input validation and sanitization
  • ORM usage for database operations
  • Content Security Policies

4. Insecure Design

Risk: Fundamental design flaws enabling attacks.

Our Protection:

  • Threat modeling during design
  • Security requirements in specifications
  • Defense in depth architecture
  • Secure design patterns

5. Security Misconfiguration

Risk: Default settings and unnecessary features.

Our Protection:

  • Hardened production configurations
  • Automated security scanning
  • Regular configuration audits
  • Minimal feature deployment

6. Vulnerable Components

Risk: Using libraries with known vulnerabilities.

Our Protection:

  • Automated dependency scanning
  • Regular update schedules
  • Software composition analysis
  • Version pinning and testing

7. Authentication Failures

Risk: Weak authentication allowing account takeover.

Our Protection:

  • Multi-factor authentication
  • Secure password policies
  • Account lockout mechanisms
  • Session management best practices

8. Data Integrity Failures

Risk: Code and data integrity violations.

Our Protection:

  • Code signing
  • Integrity verification
  • Secure CI/CD pipelines
  • Dependency verification

9. Security Logging Failures

Risk: Insufficient logging preventing breach detection.

Our Protection:

  • Comprehensive audit logs
  • Real-time monitoring
  • Log integrity protection
  • Incident response procedures

10. Server-Side Request Forgery (SSRF)

Risk: Server making requests to unintended destinations.

Our Protection:

  • URL validation
  • Allowlist for external calls
  • Network segmentation
  • Response validation

Our Security Development Lifecycle

  • Design: Threat modeling, security requirements
  • Develop: Secure coding standards, code review
  • Test: Automated scanning, penetration testing
  • Deploy: Security configuration, monitoring setup
  • Operate: Continuous monitoring, incident response

Conclusion

Security isn't a feature - it's a fundamental requirement. Every application we build at PeakCodeSolutions incorporates security from the first line of code.
